Abstract
A serializer including a pull-up unit configured to pull up an output node, and a plurality of data select units configured to receive a plurality of input data signals. Each data select unit includes a pull-up device configured to pull up the output node in response to a corresponding input data signal, and a pull-down device configured to pull down the output node in response to the corresponding input data signal.
Claims19
A serializer comprising:
- a pull-up unit coupled between a first supply voltage and an output node and configured to pull a voltage of the output node up to the first supply voltage with a first current driving capability;
- and
- a plurality of data select units commonly coupled to the output node and configured to sequentially provide a plurality of input data to the output node in response to a plurality of clock signals, each of the data select units including:
- a pull-down device configured to pull down the voltage of the output node to a second supply voltage with a second current driving capability when a corresponding input data corresponds to a first state;
- and
- a pull-up device configured to pull up the voltage of the output node to the first supply voltage with the pull-up unit when the corresponding input data corresponds to a second state;
- wherein the second current driving capability is greater than the first current driving capability.

A method of converting parallel data into serial data comprising:
- for each bit of the parallel data:
- enabling a pull-up driver to pull up a first node for each such bit in response to a first state of the bit;
- and
- enabling a pull-down driver to pull down the first node in response to a second state of the bit;
- and
- sequentially coupling each first node for each bit to an output node in response to a plurality of clock signals.
